Which one of the following cannot be polarized
Correct answer: D. Sound waves
- A. X-rays
- B. Light rays
- C. Water waves
- D. Sound waves
Explanation
The correct answer is Sound waves because they are longitudinal waves, which means their oscillations occur in the same direction as the wave travels, making polarization impossible. In contrast, X-rays and light rays are electromagnetic waves that can be polarized because they are transverse waves, where oscillations occur perpendicular to the direction of wave travel. Water waves are also transverse and can exhibit partial polarization under certain conditions, but this does not apply to sound waves.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
